Full Chart

The unit's default page, Full Chart shows all echoes scrolling across the full screen. The bottom signal scrolls across the screen from right to left. The line at the top of the screen represents the surface. The bottom depth — determined by the digital sonar — shows in the upper left corner.

If the transducer with a built-in temperature sensor is connected, a digital display for water temperature also will be shown. This temperature display can be turned on and off.

This unit has the following depth ranges: 10, 20, 40, 80, 150, 300, 600, 1000 and 2000 feet.
